# Image Skew

Skew an image horizontally or vertically by an angle between -60 and 60 degrees. The tool shears the picture with an affine transform and bicubic interpolation, so rows slide sideways or columns slide up and down while straight lines stay straight. Use it for slanted banners, perspective-style graphics, italic effects on text images and dynamic layouts. Exposed corners are transparent by default.

## Frequently asked questions

### What does skewing an image do?

Skewing slants the image along one axis. A horizontal skew shifts each row sideways by an amount that grows from top to bottom, and a vertical skew shifts each column up or down. Straight lines stay straight, but rectangles become parallelograms.

### Which angles can I use?

Any angle from -60 to 60 degrees, including decimals. Positive and negative values slant in opposite directions. An angle of 0 returns the image unchanged, and small angles between 5 and 20 degrees give a subtle slanted look.

### What is the difference between horizontal and vertical skew?

A horizontal skew keeps the top and bottom edges horizontal and leans the sides, making the image wider. A vertical skew keeps the left and right edges vertical and tilts the top and bottom, making the image taller.

### What fills the empty corners?

Skewing exposes triangular areas at the corners. By default they are transparent, and the result is a PNG with an alpha channel. Enter a hex color such as #ffffff to fill them with a solid color instead.

### How much bigger does the image get?

The canvas grows by the tangent of the angle times the other side. A 1000 by 500 image skewed horizontally by 45 degrees becomes about 1500 by 500. The finished image may be up to 6000 pixels on each side, and larger results are refused.

### Does skewing reduce sharpness?

Skewing moves pixels to fractional positions, so the tool resamples them with bicubic interpolation, which keeps edges smooth and detail sharp. The result is saved as a lossless PNG to avoid any further compression loss.

### Is skewing the same as rotating?

No. Rotation turns the whole image around its center and keeps angles intact. Skewing shears only one axis, so right angles change. Use the Image Rotate tool for straightening and this tool for slanted effects.

### Can I create a perspective effect?

Skewing gives a flat, parallel slant rather than true perspective, because parallel lines stay parallel. For many banners and cards that look is exactly what you want. For full control over scaling and shearing together, use the Image Affine Transform tool.

### Which file formats can I upload?

You can upload JPEG, PNG, GIF, WebP, TIFF and AVIF images up to 5 MB. Animated files are skewed using their first frame, and the result downloads as a PNG.

### Why does my skewed image have a soft edge?

The slanted edges fall between pixels, so the interpolation blends them with the background to avoid jagged steps. With a transparent background the edge pixels are partly transparent, which looks smooth on any page color.
